United States Patent 3,220,465 WINDOWS Henry Leiser, 3-D Windows, Inc.,Mile High Center, Room 1402, Denver, Colo. Filed May 17, 1963, Ser. No.281,157 8 Claims. (Cl. 160-92) The present invention relates to windows,and more particularly to windows having sashes which are hinged at theirlower ends for swinging movement between opened and closed positions,and which sashes have screened frames pivotally connected to their upperends.

For many years, double-hung windows and casement type windows, pivotalabout vertical axes, have been widely used in the construction ofresidential and commercial buildings. In recent years, however, suchwindows have not satisfied all of the requirements of designers,builders and users, and other types of windows have been suggested toobtain greater entry of light, better weather proofing, more attractiveappearance, or for other reasons.

vAmong the windows which have found wide spread use are the louverwindows, which are characterized by a multiplicity of glass panes, eachof which is approximately 4 inches or 6 inches high, the panes beingswingably mounted about horizontal axes for opening and closingmovements. These louver windows require a large number of parts, andthus are somewhat expensive. They. are diflicult to seal, so that louverwindows are seldom used in colder climates, except in such places asporches and breezeways. In addition, this type of window, to bescreened, requires the entire opening to be screened or else requiresattachments or the like extending from each of the glass louverelements, either arrangement being somewhat more expensive thandesirable.

In another form of window, relatively large panes were mounted invertical array, each of the panes being in clined. Generally, suchwindows were characterized by inadequate ventilation openings andinadequate screening. They were complex in construction, particularly ifthe window sashes were movable in addition to being inclined. Suchwindows generally were not secure against unauthorized removal,particularly when opened, so that entry into a building through such awindow was not prevented. Such windows also were generally diflicult toclean, particularly the outside of the window panes, and were difficultto reglaze.

An object of the present invention is to provide a window which willhave an ornamental and pleasing appearance.

Another object of the present invention is the provision of a windowwhich may be readily and adequately opened to provide ventilation intothe building.

Yet another object of the present invention is to provide a windowhaving a self-contained shading element.

A further object of the present invention is the provision of a windowproviding a minimum obstruction to the entry of light.

A still further object of the present invention is to provide a windowwhich will be secure in either opened or closed position againstunauthorized removal and which will not permit unauthorized entry intothe building in which the window is located.

Another object of the present invention is the provision of a windowwhich may be readily removed from the interior of the building to permitcleaning of the exterior of the pane, or reglazing.

Yet another object of the present invention is to provide a window whichwill be economical in construction 3,22,465 Patented Nov. 30, 1965 "iceand readily fabricated of parts and materials which are readilyavailable.

Still another object of the present invention is the provision of amultiple-section wind-ow permitting indirect ventilation of a roomthrough each section thereof.

A further object of the present invention is to provide a window whichwill prevent accidental falling therefrom or therethrough, as bychildren.

Still another object of the present invention is the provision of awindow meeting the above desideratum and including a screen which ismoved into position when the window is opened.

Other objects and the nature and advantages of the instant inventionwill be apparent from the following description taken in conjunctionwith the accompanying drawings, wherein:

FIG. 1 is a vertical cross-sectional view, with parts broken away, of awindow in accordance with the present invention.

FIG. 2 is an enlarged view of the area designated by the arrow 2 on FIG.1.

FIG. 3 is a view similar to FIG. 2, but with the parts in a differentposition.

FIG. 4 is an enlarged view, with parts broken away, of a lockingarrangement for the window of FIG. 1.

FIG. 5 is a perspective view of a portion of the window of FIG. 1,showing a security lock.

FIG. 6 is a cross-sectional view taken on the line 6-6 of FIG. 5.

FIG. 7 is a cross-sectional view taken on the line 77 of FIG. 1.

Referring now to the drawings, wherein like or corresponding parts aredesignated by like or corresponding reference characters throughout theseveral views, there is shown in FIG. 1 a window generally designated 10comprising a header 11, a sill 12 and a pair of jambs, jamb 13 beingshown. The several parts of the window, including the sashes, arepreferably made of extruded aluminum. Header 11 and sill 12 havecrescent shaped channels 16 integrally formed thereon, as during theextrusion process by which they were made, to provide receiving elementsfor screws. By this construction, the jamb 13 may be secured to header11, for example, by screws inserted through the jamb 13 and screwed intothe crescent shaped channels 16, one such screw being shown at 17.

Header 11 has near its outside edge a groove 18 into which extends aflange 19 of a drip cap 20. As may be seen, drip cap 20 extendsoutwardly and downwardly from the outer edge of header 11 and has alower horizontal flange 21. The end of the drip cap 20 is closed by asuitable plate 22.

A fixed shelf 25 extends inwardly from the drip cap 20, and lies in aplane parallel to and below the header 11. At its outer edge, as shownin FIG. 2, fixed shelf 25 has an upstanding flange 26 with an uppercurved end 27. Extending inwardly from flange 26 is an abutment 28, andbelow the free extremity of curved end 27 is a recessed portiongenerally designated 23.

Referring again to FIG. 1, it will be seen that shelf 25 has at anintermediate part thereof an outwardly facing hook element 29, and atits inner edge has another outwardly facing hook element 31 (see alsoFIG. 4) and a groove 32, in which is lodged a longitudinally extendingweather strip 33.

A second, intermediate fixed shelf 25 is positioned generally below andparallel to the upper fixed shelf 25, and has the same shape. A sideplate 35, of generally triangular configuration, is secured to the jamb13, and has at its outer, inclined edge a laterally inturned flange 36(see FIG. 7) with a recess 37 therein which receives weather stripping38. As will be understood, there is a similar side plate and side railopposite the side plate 35 and side rail 36. The side rail 36 isinclined, and extends from the inner edge of the upper shelf 25downwardly to the outer edge of the intermediate shelf 25.

A glazed sash 49 is provided, formed of extruded aluminum sections andincluding a bottom rail 41 which may be seen in FIGS. 2 and 3 to includean outer flange 42 and an oppositely disposed inner flange 43 definingbetween them a groove having a pair of arcuate connecting portions 44and 45 separated by an opening 46 in which is weather stripping 47having an outer face which connects the arcuate portions 44 and 45. Atthe lower end of the inner flange 43 is an outwardly facing flange 48.The curved end 27 of fixed shelf 25 forms a bearing surface for thebottom rail 41 of sash 40, so that sash 40 may pivot, as between thepositions shown in FIGS. 2 and 3. As will be understood, the arcuateportions 44 and 45 will bear upon and be journaled on the curved end 27,and the arcuate face of weather strip 47 will always be in contact withthe outer surface of curved end 27. As shown in FIG. 3, movement of thewindow in an opening direction is limited by the engagement of flange 48with abutment 28. In addition, translational movement of sash 40 awayfrom the curved end 27 (upwardly and to the right asshown in FIG. 2)would be stopped after a limited amount of movement by engagement offlange 48 with the free extremity of curved end 27 of flange 26.However, when sash 40 has been moved to the position shown in FIG. 3, inan opening direction, with recess 23 permitting movement of sash 40without engagement of flanges 43 and 48 with the lower part of fixedshelf 25, the entire sash 40 may be removed from engagement with fixedshelf 25 by sliding it in its plane generally upwardly and to the rightas seen in FIG. 3. Separation is permitted because flange 48 will notstrike the free extremity of curved end 27 since it will clear the freeextremity of curved end 27 as the entire sash 40 is moved on a bearingengagement between the underside of flange 42 and the outer surface ofcurved end 27.

At its upper edge, sash 40 has an upstanding flange 51 (see FIG. 4) witha generally cylindrical terminal portion 52, and a lug 53 immediatelybelow terminal portion 52. Below flange 51 is a second upstanding flange54 having a latch device 55 secured to it, at approximately its lateralmid point. Latch device 55 includes a housing 56, parts of which areshown broken away, with a handle lever 57 pivoted at 58 therein. Handlelever 57 terminates within the housing 56 in gear teeth 59 which are inmesh with gear teeth 61 on a latch element 62. Latch element 62 ispivoted in the housing 56 at 63 and has a hooked end 64 which may beengaged with the hook element 31 of fixed shelf 25.

A frame 65 having the screen 66 (see FIGS. 4 and therein is providedwith an inner rail 67 having a longitudinally extending cylindricalrecess 68 which receives the cylindrical portion 52 of sash 40, tothereby permit relative pivotal movement between sash 40 and frame 65.Such pivotal movement is limited by the lug 53. The frame 65 may beseparated from sash 40 merely by sliding movement along the axis ofcylindrical portion 52. Along its outer edge, frame 65 is provided withan inwardly turned hook element 69 which may engage either hook element29 of fixed shelf 25 or with hook element 31 thereof as is shown in theupper portion of FIG. 1 to hold the sash 40 in partly opened or fullyopened position.

A security lock '70 is provided and comprises a spring strip 71 (seeFIGS. 5 and 6) secured at one end by a rivet 72 to the jamb 13 andhaving at its other end a slot 73 which receives a head 74 of a pin 75.Pin 75 extends through a hole 76 in jamb 13 and has a large, flattenedhead 77 on the side of jamb 13 opposite spring strip 71. Consequently,and as Will be understood, the pin 75 may be pushed to the dotted lineposition, against the force of spring strip 71, to thereby permit thesash to be rotated in an opening direction (clockwise, as shown). Aswill be seen from the upper section of FIG. 1 and from FIG. 6, the sash4G is in its fully opened position, with hook element 69 of frame 65 inengagement with hook element 31 of fixed shelf 25. In this position,sash 40 does not contact security lock 70, but is slightly spacedtherefrom. Also, in this position, the bottom portion of sash 49 is insubstantially the position shown in FIG. 2, relative to curved end 27.

The sash 40 in the lower section of window 10 is shown in the closedposition, and it will be seen that the hooked end 64 of latch device isin engagement with the hook element 31 (see also FIG. 4) of intermediatefixed shelf 25. The frame 40 is pressing against weather stripping 38 inthe side rails 36, as is seen in FIG. 7, the weather strip 47 in theframe 40 is against the curved end 27 of the lower shelf 25 and at itsupper end the frame 40 presses against the weather strip 33 inintermediate shelf 25. There is thereby provided a completely secure andweather proof closure. The frame with its screen 66 is stored above theintermediate shelf 25, its outer end resting on intermediate shelf 25 aspermitted by the free pivotal movement between frame 65 and sash 40. Thesash 40 is thereby inclined, having a pleasing and distinctiveappearance and is secure against unauthorized entry in this position.The frame 65 is stored in an out of the way position, and one whichpermits the sash 40 above it to be opened, as shown in FIG. 1.

When it is desired to open the sash 40, the handle 57 of the latchdevice 55 is manipulated to raise the end 62, thereby permitting thesash 40 to swing inwardly, pivoting on curved end 27 of shelf 25. Toprovide for an intermediate opened position, the hook element 69 offrame 25 may be engaged with hook element 29 of fixed shelf 25, or thesash 40 may be moved to the fully open position, which is shown in theupper portion of FIG. 1. In this position, the hook element 69 of frame65 engages with the hook element 31 of fixed shelf 25. While the sash 40and frame 65 may be manipulated from the outside, with eventualdisengagement of hook elements 31 and 69, and further clockwise rotationof sash 40, sash 40 may be rotated in an opening direction only until itengages with the two security locks 70. Further opening movement of sash40 can then be accomplished only by depressing security locks as abovedescribed, and this can be accomplished only from within the building;frame 65 may be rotated a limited amount as rotation is restricted bylug 53. Thus, an intruder could only effect movement of the sash 40inwardly until engagement with security lock 70. Further, the sash 46may not be removed from engagement with fixed shelf 25 because securitylock 70 will prevent it from moving to the position shown in FIG. 3 inwhich it can be withdrawn from such engagement by translationalmovement.

There has been provided a window construction having an attractive anddistinctive appearance. This construction may be readily fabricated, andas will be understood all materials used therein are readily accessible.While children and others having a tendency to lean against a windowcould fall out of ordinary windows, such action would only tend to closethe window of the present invention. The sash may be removed from thewindow after manipulation of the security lock from within the building,to thereby permit cleaning and reglazing of the sash. The ventilationobtained is indirect, adequate, variable and independent from sash tosash. The window herein provided is fully weather stripped.

It will be obvious to those skilled in the art that various changes maybe made without departing from the spirit of the invention and thereforethe invention is not limited to what is shown in the drawings anddescribed in the specification but only as indicated in the appendedclaims.
